Question

the magnitude of force required to increase the velocity of an object to 10 m/s having mass of 2kg
a. 2N
b. 5N
c. 10N
d. 20N​

Answer 1

Answer:

AS WE KNOW THAT FORCE = MASS × ACCELERATION

IN THIS CASE WE DON'T HAVE ACCELERATION SO WE USE ANOTHER FORMULA THAT IS

FORCE =change in linear momentum

F=m(v-u)

F=2×(10-0)

F=20N
